Configuring a Channel Off (Figure 2-10)

The instrument is protected from channel configuration errors. For example, accidentally
applying 300V ac to a channel configured for resistance will not damage the instrument.

Perform the procedure in Figure 2-4 to configure a channel for measuring dc volts. In
preparation, the instrument must be in the inactive mode (not scanning or monitoring)
and the desired channel must be selected (see Figure 2-3). To exit at any time (changes
not saved), press the 

C key.

Restrictions

Maximum Input. The maximum voltage inputs are 300V dc for channels 0, 1, 11, and
150V dc for channels 2 to 10, and 12 to 20.

90.000 mV Range. Not used in Auto (autoranging).

Required

Selecting the DC Volts Mode.  Press the FUNC 
key to access the SET FUNC (Set Function) 
menu.  Press the up/down arrow keys until V DC 
(volts dc) is displayed, then press the ENTER 
key.

Selecting the Measurement Scale.  Select a 
fixed scale or Auto (autoranging).  A fixed scale 
indicates an upper measurement limit.  For 
example, the 30.000 V scale measures 30 volts 
or less.  Measurements beyond the scale limit will 
cause an OL (overload) display.  The x1 (1.0) 
multiplier indicates a reading in volts dc; the m  
multiplier (0.001) indicates a reading in millivolts 
dc.  A 900.00 mV range is available by computer 
interface and may appear in the display if this 
was previously selected.

In Auto (autoranging), the instrument chooses the 
scale for the best measurement resolution.  
When the scales are changed, the scan is 
momentarily slowed.

*  Depends on temperature scale.
**  Channels 0, 1, and 11.
*** Channels 2 to 10, and 12 to 20
